Unlike general anesthesia, in which the goals are well-defined – no pain, no consciousness, no memory – conscious sedation is in some so a gray area, where the boundaries between consciousness and unconsciousness are unclear, where we sometimes expect patients to be half awake and responsive, and where their distress could possibly be ignored, because amnesia usually installs.
"With conscious sedation, I think doctors recognize a lot of time, their patients will actually be in distress, but they rely on the fact that most will not remember it," he said. Dr. Davidson. This is obviously not the goal, he added, "but it's hard to get the right dose." As he wrote in the Journal of Medical Ethics, "In many cases, the patient grimaces or wiggles during the procedure – some will even say it hurts." But "the vast majority do not remember anything"
In my case, plagued by my painful memories, I was diagnosed with an acute stress disorder, a transient form of PTSD I spoke to a therapist, I was told that I had been diagnosed with it. I asked my doctor for clarification and I looked for ways to avoid a negative experience next time.
But if, like most people, I had Forgotten panic and struggled table Would I still have experienced nightmares and anxiety without any explanation? And can a person with a tendency to depression or anxiety trace his problems to forgotten experiences under sedation? ?
"There is plenty of evidence" that even without a stave In an explicit sense of surgery, humans can form implicit or unconscious memories under anesthesia, said Dr. Aeyal Raz, anesthetist at the University of Wisconsin. "There is a trace of the event, a memory left in the brain. However, it is impossible to access it with conscious thoughts and the person does not remember the learning event. Nevertheless, this can affect future feelings and behaviors. "
" Research in psychology suggests that even this very rudimentary memory activity can have profound effects on behavior or emotions, "wrote Jackie Andrade, psychologist at the University of Plymouth., in a review of the subject. "It seems plausible that negative experiences during a surgical procedure may reduce the well-being of patients in the recovery phase, but this is difficult to prove," he said. she said.
But Dr. Davidson believes that implicit memory after anesthesia is obvious. "Very mixed, and it's a very long arc to draw to say that it has lasting effects. "
